I am going to purchase one of the GP gee bee arfs as soon as they come available. I am trying to figure out what engine to use though. I reall want this plane to haul *****. I like the sound of four strokes, thinking about a os fs 120, ys 1.40, or a saito 1.50 or 1.80. But will these engines make this plane really perform. Maybe an os 1.40 or 1.60 two stroke? I don't know maybe an rcs140. what engines do you think this plane go the fastest.

The recommended engine is the OS 1.20 FS. That's what I'm putting in mine. But if you want more power, I'd find the weight of the OS 1.20 and then shop for more displacement at the same or less weight . Be very careful not to bolt too much more weight onto the firewall and then add lead to the tail to get it to balance! Your wing loading will shoot up quickly and then you will have a very fast, poor flying airplane. The wing loading is already very high on the Gee Bee assembled as stock.

I just started flying my 1/4 scale GeeBee R1 built from Henry Hafke plans It weighs 15#. I tried an OS 120 pumped engine for the first flight. It didn't quite have enough power, but the plane flew after a long takeoff run. I now have a Saito 180 swinging a 16-8 APC prop, and does it perform now. About a 30 foot run, and takes off in a 3 point attitude. I do loops, rolls, 4 point rolls, slow fly, etc.
This plane is not a killer aircraft as everyone has been led to believe. Actually in the air, it's a *****cat. But it does like to nose over on landing. You must slow it way down close to the ground, and kick in a lot of up elevator(I click on high range on my transmitter as I get near the ground). That's the only bad feature of the GeeBee. Slow it down.
Good luck on your GP geeBee. It should fly great.

Does youR GeeBee have a scale wing or was it redesigned. On a scale model they must be landed fast othwise it will snap on landing. That's the killer trait that gave the GeeBee it's bad name. Be careful when landing the GP GeeBee...Not sure which wing it has either.

My GeeBee was designed by Henry Hafke twenty years ago. It appeared in Model Aviation as two articles in 1983. Henry is considered the Guru of GeeBees as he has drawn them all up and they all fly good. The plane appears to be vey scale like.
Yes, it lands fast, but is very managable. No snaps. I don't want a plane that is so scale it snaps on landing. Sorry. Right now I am real satisfied with the look and flight qualities of my bird.
Knowing Great Planes like I do, I think their new GeeBee R2 will be another winner. Don't damn the plane before it flys.

I'm not damning it by any means....but the last time a major manufacter released a model of the geebee it was a total flop. I'm currently building a R2 designed and kitted by adrian page.


The the GP R@ is being advertised......


Recommended for modelers who have had trainer airplane experience and also have safely flown and landed low wing sport planes.....

that comes directly from tower hobbies.....there are going to be many of these planes wrecked because of this. Inexperienced pilots will try to fly it and crash on landing becasue of too low approach speed.

I'm just giveng people a heads up that would happen to read this thread becasue it seems that there are more and more of the planes popping up. That's all,

If you haven`t` already done it go to Great Planes web site & down load the Gee Bee instructions, there are some interesting notes on flying & landing. Gives a few hints as to what you might expect, looks like a real handfull, but I still must have one !
